Specification of Letters Patent. Patented July 21, 1914,

Application filed May 23, 1912. Serial No. 699,189. i

T 0 all whom it may concern:

Be it known that I, THOMAS H. MoAUL- lFFE, a citizen of the United States, residing at Lynn, in the county of Essex and State of Massachusetts, have invented certain Improvements in Lasting-Machines, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to lasting machines and more particularly to lasting machines of the type described in United States Letters Patent No. 584,744, dated June 15, 1897. Lasting machines of the type described in said prior Letters Patent and commonly known as hand method lasting machines have usually employed a reciprocating presser or wiper for stretching and laying down the edge or margin of the upper around the toe to force the upper into the angle of union between the feather-edge and lip of the inner sole, herein sometimes designated the sole said terms being intended to include the single sole of a turn shoe as well as the inner sole of a welt or other shoe having inner and outer soles. By this means the upper is worked into proper position to be secured by temporary tacks or by a wire binder and at the same time the plaiting action of the pincers is materially assisted. The reciprocating presser in its forward movement is, however, apt to strike and mar the edge of the upper and to break and mu tilate the feather-edge of the sole. Frequently, too, the action of the reciprocating.

presser in thus creasing the upper into the angle between the feather-edge and lip 01 the sole results in tearing the leather, espe cially if it be thin or tender leather such for example as is frequently the case with patent or enameled leather. Moreover, when the wiper is retracted the stretched portion of the upper is very likely to slip back more or less. To correct these various defects and to obviate these disadvantages several constructions have been devised. It has been proposed to employ a circular disk wiper with an unbroken and smooth periphery and arranged to have a continuous rollingengagement with the upper. Ithas also been proposed to make use of a rotatable diskshaped wiper with its periphery scalloped to form peripheral fingers, these fingers being better adapted to engage and hold the stock firmly and to work it into the desired position than the smooth periphery of the former wiper. In the use ofthis scalloped wiper heretofore it has however been arranged to be actuated intermittently between successive plaiting movements of the pincers and ithasfibeen found in practice that although this form of wiper is much more efiicient in bending down and holding the upper materials in place than either of the wipers before mentioned, nevertheless its eificiency is limited because, like the reciprocating presser, itsoperation is intermittent.

I have discovered that improved results can be obtained by'actuating the wiper to bend and break down into place the stiff upp'ermaterials in advance of the folding over and laying of the plaits by the pincers and also for further rubbing the upper in lasted position after each plait is formed and laid.

By the additional action of the wiper on the stock thus provided in accordance with this invention the work of the pincers is facilitated and also the upper after being left by the pincers is further treated to form it permanently in its lasted position. Moreover, around the toe of the shoe which is the portion for which the wipers are particularly intended the bulky upper materials stand out stiiily from the last and a greater and more constant pressure can be advanta-' geously employed to crease the stock into the angle between the feather-edgeand lip of the sole than can be given by the intermittently operated presser.

Accordingly with a view to improving the construction and operation of the abovementioned forms of wipers, the present invention contemplates the provision of means 7 In the embodiment of the invention here connect and disconnect the wiper from its actuating mechanism. v

A feature of the present lnvention consists in the fact that the wiper by reason of its continuous rotation in'engagement with the upper operates particularly successfully to place the toebinder in binding relation to the. upper. Furtherl'nore the continu,' ously rotating wiper 'by constantly engaging the upper to strain and stretch it into place relieves the pincers of a large part of the upperstretching and consequently cooperates most effectively wit-h the pincers thus facilitating greatly their work.

It should also be n'oticedas a further feae ture that the present invention-as prefer-'- ably embodied is peculiarly adapted for holding the stock firmly to "prevent any slipping back or unfolding of the plaitedj and'stretched portions of the upper These and other features-and advantages; of the present invention will be apparent;

from the following detailed description" read inconnect-ion with the drawings which show one illustrative embodiment ofthe invention. f Referring to the drawings :-Figure 1 is a side view in elevation'of a portion of a; lasting machine of the type referred to,

with the present invention applied theretoj Fig. 2 is a top plan view of therotatable wiper and its associated partsincluding-the mechanism for actuating the wiper Fig. 3 is a detail of the actuating mechanism for the wiper; Fig. 4 is a detail of the mecha-' nism for disconnecting the wiper from'its actuating mechanism; and Fig. 5 is a section taken on the line 5-5 of Fig. 2. l

The machine to which by way of illustra-l tion this invention is described as being ap plied, comprises a column A whichsupports a framework or head 13' on which are mount;

ed the various operating parts of the ma chine-and in which is journaled the main cam shaft D (Fig. 1). The cam shaft D has upon it the cams and gears which give the proper motions to the several mecha';-

nisms for operating the various lastingdevices. 1

The pincers 14c, 16 are mounted at the.

. front of the machine and are operated by 1 suitable mechanisms to descend and grip the edge of the upper, then to rise and stretch the upper and then to move downfwardly and forwardly toward the middle portion of the innersole'to lay-the stretched portion of the upper down in position to receive a fastening tack. Tacks are supplied by a double raceway 18 adjustable to feed different sized tacks to the tack-carrier or tack-block 20, the tack-block 20 also servr ing as a presser to hold the stretched and V laid upperin tack receiving position for the insertion of the tacks after the grippers have retreated preparatory to again stretching and over laying another portion of the upper.

In addition to the pincers movements :above referred to, it'is necessary at times, particularly in lasting around the toe, and

sometimes at other points to give the pinceI's. other movements to fold or plait the upper in order to dispose of the fullness of upper materials at those points. in order to thus movethe pincers to plait the upper at the toe, suitable mechanismoperated from a cam on the main shaft is provided, this mechanism including adjustable means for rendering the plaiting means operative or inoperative as desired through movement of a knee lever 22 which turns a rockshaft 24:, movement of" the rockshaft 24 in turn through suitable connections operating a slidlng block 26 for startlng, stopping andcontrolling the lateral and turning or plaiting movements of the pincers. I

For a full disclosure of the complete machine to which the present invention is described as being applied and for a complete description of the construction and operat1on of the above mentioned mechanlsms and parts, reference should be had tosaid prior Letters Patent No. 584,744 Reference should also be had to said patent for all other details of construction and of operation ofjparts not fully described herein since except as hereinafter indicated and described in detail the construction and Opera tion may-most conveniently'be as described and explained in said prior patent.

As above stated it is necessary in lasting around the toe and sometimes at other points to employ a wiper or presser-tobend down the stiff outstanding upper materials and to crowd the upper down into the angle of union between the feather-edge and lip of the inner-sole. For this purpose, preferably a rotatable wiper or presser 28i s employed, the wiper 28 being substantially like that above referred'to. The wiper 28 is located in a plane below the intermediate plate B of the machine and slightly below the track-carrier 20 (Fig. 1). The wiper 28 has a hub 30 by which it is rotatably mounted in a plate 32 which is in turn secured as by bolts orthe like to the underside of the pivotally mounted wiper carrier 34. The carrier 3a is cutaway at 35 to overlap and partially cover 'the wiper 28.

The carrier 34 is pivoted on a boss 38 on the intermediate plate B (Fig. 1) being held on said boss by a cap plate 40 and a screw 42.

In order that the wiper may be adjusted into and out of operative position the carrier 34 is provided with an arm 36, the arm 36 having gear teeth meshing with similar teeth on an arm 39 0f the rock shaft 24 above mentioned. From this it will be seen that whenever the knee lever 22 is moved to actuate the rock shaft 24 for throwing the plaiting means into and out of operation as above stated and as fully described in said prior patent, the wiper carrier 34 will at the same time be automatically adjusted to swing the carrier 34 and the wiper 28 about their axis either'into the operative position shown in Fig. 2 for lasting the toe or re versely and backwardly out of operative position when the heel and sides are being lasted and it is not desired to use the wiper. Cooperating stops may conveniently be placed at 41 and at 43 to limit the outward movement of the carrier 34 and a spring pin 44 mounted in the rocker arm 38 engages shallow recesses 46 in the under face of the intermediate plate B to retain the presser in adjusted positions.

The presser 34 has its periphery scalloped to form fingers 48, these fingers being slightly cut away or beveled on the under side and being as before stated peculiarly adapted for engaging and creasing the upper into the angle 49 between the featheredge and lip of the inner sole (Fig- 2) as well as for permitting the driving of the tacks between them, if tacks are employed to secure temporarily the upper in lasted position. In lasting Goodyear or welt shoes it is, however, commonly the practice to secure the upper in lasted position around the toe by means of a wire toe binder w (Fig. 2), the wire being supplied from a reel conveniently located on the machine and being guided by an arm 50, the guide 50 being attached t0 the plate 32 so as to be moved to and from operative position simultaneously with the adjustments of the wiper 28. The wiper 28 in addition to wiping the upper into the angle 49 alsooperates as a presser and by engagement of the vertical edges of the fingers 48 with the wire to, the wire w is presed downwardly and inwardly into the said angle 49 as clearly shown in Fig. 2. Moreover the beveled formation of the fingers 48 permits them to slightly overlie the wire and thus to press it into position positively and effectively, as'shown in Fig. 5.

The operating mechanism for rotating the wiper 28 is actuated by a spiral gear 52 on the main shaft D. A similar gear 54, shown in dotted lines in Fig. 1 and in full lines in Fig. 2, is arranged to engage the gear 52. The gear 54 is fixed on a vertical shaft 56 (Fig. 3) and the shaft 56 carries at its lower end a fixed bevel gear 58. One arm of a bracket hanger 60 embraces the shaft 56 just above the gear 58 while the other and depending arm of the hanger 60 serves as a journal bearing for one end of a horizontal shaft 62. A bevel gear 64 with its teeth intermeshing with the teeth of the gear 58 is loose upon the shaft 62 and a clutch device is provided as will be explained below for causing the shafts 56 and 62 to rotate together when desired. Secured to its other end the horizontal shaft 62 carries a bevel gear 66 which meshes with a companion gear 68 fixed to the under side of a spur gear 70. The spur gear 70 meshes with a pinion 72 fixed to the under side of the wiper 28 and through which the hub 30 of the wiper 28 passes. Hence it will be seen that whenever the shaft 62 is rotated by means of the above described gearing the wiper 28 will likewise and simultaneously be rotated.

It will be observed that whenever the machine is running, the shaft 56 which is operated through connection with the gear 52 on the main shaft D will be continuously rotated and if the shafts 56 and 62 were arranged to be always rotated together, it would follow that the wiper 28 would be continuously rotated whenever the machine is in motion. To prevent the unnecessary wear of machine parts which would thus be occasioned, as above stated, the gear 64 is loose on the shaft 62 and a clutch device is provided for causing the shaft 62 to be rotated with shaft 56 when desired. This clutch device preferably comprises the toothed member 74 fixed with relation to the gear 64 and the correspondingly toothed companion clutch member 7 6 which, as shown in Fig. 4, has a pin and slot connection with the shaft 62 by which it is permitted a certain amount of lengthwise movement along shaft 62 but is prevented from turning on the said shaft. To cause the clutch members 74 and 76 to be brought into clutching engagement with each other the shaft 62 is mounted for longitudinal or lengthwise movement in its hearing so that movement of shaft 62 to the right (Fig. 3) will bring the clutch members into the disengaged position shown in Fig. 4 while movement of shaft 62 reversely to the left again will bring the clutch members into engagement as shown in Fig. 3. As shown in Fig. 2 these connections of the wiper with and disconnections from its actuating mechanism are preferably made to occur simultaneously with and by reason of the adjustments of the wiper 28 to and from the operative position of Fig. 2 by reason of the fact that whenever the wiper is swung from the position of Fig. 2 backwardly to its retreated and inoperative position the plnion 72 on the wiper 28 will necessarily through engagement with the gear on the sliding rod 62 push the shaft 62 backward thus forcing the clutch mem' bers apart into the disengaged position shown 1n Fig. l while movement of wiper 28 to the front again will cause shaft 62 to be pulled forwardly until tne clutch members 74 and 76 are again in clutch .en-' gagement.

To insure that when the members 7 4i and 76 are brought into engagement the teeth of each will register in the opposite recesses of the other a fairly stiff spring 78 is coiled within the clutch member 76 around the fail properly to register, as soon as the clutch member 74: is turned enough to permit, the teeth of the clutch member 76 will be pressed forward into engagement with the corresponding recesses in the member 7%.

From the above description it will be apparent that by reason of the continuous rotation of the wiper 28 while it is in operative position, taken in connection with its scalloped and beveled formation, not only will it act positively and powerfully to crowd the upper inwardly into the angle 4C9 before the pincers seize it but also during the interval between the release of one portion of the upper by the pincers and the seizure of afresh portion the wiper will actively operate to gather the fresh portion of theupper inwardly toward lasted position and to rub down upon the shoe bottom the portion released by the pincer-s. The wiper thus acts in a twofold manner as a supplementary lasting means. As the pincers move laterally in the direction to carry the upper in under the wiper, or into the angle between the wiper and the body of the shoe, the wiper bites and assists to gather inwardly the plaited upper while the scalloped projections of the wiper, as it is continuously rotated act by impact to drive the upper against the lip or shoulder of the innersole. In this manner the upper is set in lasted posit-ion by rapidly repeated blows of gradually increasing closeness ofcontact directed horizontally against the stock. Furthermore, the difficulty previously experienced in distributing the fullness of the upper evenly either side of the center of the toe so as to prevent unsightly bunches and folds is almost entirely obviated by the use of my invention. By its constant rotation in engagement with the binder w, the wiper moreover will press the stiff wire into place in a manner heretofore unknown. At the same time, convenient and practicable means are provided for automatically adjusting the wiper to and from operative position with the throwing in and out of the .plaiting means and for simultaneously connecting and disconnecting the wiper with and from its operating mechanism.
